Any information or experience with the RoadBurner Touring Pro pipes for a 2007 FLHX with SE Stage I (possibly a bolt-on 103" down the road)?

I'm thinking of going with a "True Dual" type exhaust system and these look interesting. They feature a "stepped" design, which makes sense to me, but where I get confused is with the elimination of the crossover "Y" pipe.

One of the reasons I want to go with a true dual is because I want to get rid of the "Y" pipe connection and the crossover under the seat. I'm mainly concerned about heat, but I don't want to lose performance because of it.

Most of the true dual manufacturers seem to claim better performance with a fully functioning rear pipe. But I've also seen folks say that you lose performance when you eliminate the crossover.

Does it really make a difference in performance, or is it all a matter of tuning?

It's a matter of the true dual design. Many TD systems actually hurt performance vs. the Y pipe system with a good slip-on. Some do work, however, and those are mainly the stepped systems. As you add cam overlap, the unrestricted stepped systems tend to lose low end torque but make great peak numbers. We do not have experiance with the Roadburner system, to date.
